Hi all,Since a few days i got on our standby continious replication server errors on the System attendant mailbox and MSExchangeFBpublish. The event-id's are 4001 for the system attendant and 8213 for the MSExchangeFBpublish function. All databases are mounted and no other errors are reported. I already restarted the system attendant service with no luck. I do not find any relevant info about these specific errors. What could be wrong here?Thanks in advance,Laurens.the actual event viewer entries are here below:Event Type: ErrorEvent Source: MSExchangeFBPublishEvent Category: General Event ID: 8213Date: 8/01/2010Time: 11:07:01User: N/AComputer: FEBEXCHANGE02Description:The Microsoft Exchange System Attendant service failed to create session for virtual machine FEBEXCHANGE02.

I found that the PF database was dismounted on the production server. I could mount the database but the problem was not solved. On our production server i have now the event 102 on the MSExchange Store Driver every minute. The error you find here below.

Hi Laurens, Did you ever resolve this problem? If so, how? We are experiencing the same issue currently and have not found a solution.TJR

Try to restart the Microsoft Exchange Active Directory Service. See if that resolves your problem. The error specifies that the Store Driver is not able to establish a connection to the Server. Also try Disabling the Windows Firewall on that Server.Ashwin Raj
